APPARATUS FOR PRODUCING OZONE.

To alt whorn it may concern:

Be it known that I, ALBERT 0. W001), a citizen of the 'm'ted States, residing at Philadelphia, int-he county of Philadelphia and State of. Pennsylvania, have invented 'certaln Improvements in Apparatus for Produc1 Qzone, f which the following is a speci cation. ,1 This invention relates to the production of ozoneor of ozonized air through the action of the silent or brush discharge ofa high or charge in an atmosphere of oxygen or air, audit is a division of "my application dated October 18, 1904, SerialyNo. 228,941. Theleading objects are to produce an apparat us; of high capacity andeflic-ieney which will effect a uniformly distributed discharge of electricity into circulating air, to provide a simplified-construction having parts that; are self alining and reversible and that may readilybe assembled and disassociated, and to provide an improved electrode having a lining of higlllilly oxidizable metal.

represents an end elevat on of the construction shown in Fi 1, Fig. 3 represents a longitudinal sectiona view through a detached tubular electrode having therein coacting brush electrodes with their supporting means, Fig. 4, represents a longitudinal sectional. view of a second form of the invention, Fig. 5 represents a longitudinal sectional view of a modification of the construction shown in Fig. 4, Fig. 6 represents a transverse sectional View of the construction shown in Fig. 3, Figi o the construction shown in Figs. 4 "and 5, Fig. 8 represents a sectional view and F ig. 9 a face view of. the insulating caps or end supports for the brush electrodes, Fig. 10 represents a sectional view and Fig. 11 a face view of an insulating support or spider for the brush electrodes. r

Referring to the drawings, the apparatus comprises a chamber 1, having an air inlet 2,

and an opening 3, which receives an insulator engage the forward ends of the rods 7, and

bear, against the insulating which the rods project. The caps 8, having caps 8 through Specification of Letters Patent. Original application filed October 18, 1904,'Seria1 No. 228,941.

the apertures 9 therein, fit into and engage the forward ends of the several tubes 10 which pass into the chamber through the wall or diaphragm 11 thereof. The op 0- site ends of the-tubes pass into the cham er 12 through the wall or diaphragm '13 thereof, the chamber having an outlet '14. The rods 7 have loosely sleeved thereon intermediate of their length the apertured insulating disks or spiders 15 which are freely movable in the tubes and serve to center and su port the ends of the brushes carried there by. The rearward ends of the rods are centered and supported by apertured insulating disks or spiders 16 loosely fitting the rearward ends of tie tubes.

As shown support the nickel brushes 17, having their planes disposed radially and longitudinally with reference thereto. The tubes'lO are preferably of circular section and made of copper with a lining 10 of nickel or other non-corr'odible metal.

As shown in Figs. 4, 5 and 7, the rods 7 are provided with the nickel covering 7 and have sleeved thereonthe nickel brushes 18 of circular or disk form with peripheral points or serrations 19. The disks or spiders are held in position by the sleeves 20 placed on, the rods in abutting relation to the disks, the

end sleeves being forced in to clamp the and the caps 8 on spiders 16 and the ends.

As shown in Fig. 5 the tubes 10 are provided with nickel'inserts or rings 21, having a low coefiicient of oxidation, which are nut 16 on the rearward in Figsfit 3353's, the rods 7" the binding connections 6. the forward ends and the arranged around-the disks to collect the discharges therefrom, the nickel rings alternating with spacing rings 21 which may be composed suitably of 00 per.

It will be understoo that current from the wire 5 is distributed by the connections 6 and the rods 7 to the brushes 17 or-18 and the discharge therefrom is collected by the nickel lining, whether-in the form of a sohd shell or inserted. rings, and carried off.

through the wire 5. 1

From the fore oing it will be. understood that air admitte inlet 2 is carried through the'perforated msulating caps 8 and the tubes 10 asals the perforated insulating dfsk's- 15 and 16 into thechamber 12, from which it escapes by the into the chamber 1 by the ioo outlet In the passage of the air through the tubes it is subjected to the action. of w hat is known as a silent or brush discharge produced by a high tension electric current or charge of electricity discharging between the conducting rods 7 and the electrodes or conducting tubes 10 by the brushes 17 or 18, the brushes being centered so as to effect a uniform discharge of electricity (with the absence of sparking or arcing) across the air current, Whose ozonification is obtained thereby.

Having described my invention I claim:

1. In apparatus of the class described a mechanism providing a conduit and an electrode through and in contact with which oxygen is passed, said mechanism having a metal body and inserts of highly refractory metal more ditficultly oxidizable than the metal of said body, in combination with a second electrode and means for discharging electricity betweenthe second electrode and the inserts, substantially as described.

2. In apparatus of the class described a mechanism providing a conduit and an electrode through and in contact with which oxygen is passed, said. mechanism having a metal body with rings therein of highly refractory metal more difiicultly oxidizable than the metal of said body, in combination with a second electrode and means for dischar ing electricity between the second electro e and said rings, substantially as specified.

3. In apparatus of the class described a U ii'gi i i 3 Lilli mechanism providing a conduit and an electrode through and in contact with which oxygen is passed, said mechanism compris ing niclrel rings and spacing rings alternat ing therewith in combination with a second electrode and means for discharging elec tricity between the second electrode and said nickel rings.

4. In apparatus of the class described a mechanism providing a conduitand an electrode through and in contact with which oxygen is passed, in combination with a second electrode comprising a disk or disks be tween which and said first electrode electricity is discharged.

5. ln apparatus of the class described, a mechanism providing a conduit and an electrode through. and in contact with which oxygen is passed, said mechanism having a metal body and a lining of highl refractory metal more diliicultly oxidizab c than the metal in said body, in combination with a second electrode and means for efl'ectin an electrical dischar e between said 'secon electrode and said lining, substantially as specified.

In testimony whereof I have hereunto set my name this 10th day of May, 1906, in the presence of the subscribing witnesses.
